How does it work?

We will send a professional energy analyst to your facility to conduct an Energy Audit using the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) guidelines.

The Energy Audit is free and provides information on your facility’s energy performance and offers details to help prioritize investments in energy-efficiency upgrades. These investments will help reduce energy use and operating costs of your business.

The audit involves:

  • Collecting and studying historical energy usage
  • Studying the building’s operational characteristics
  • Identifying and analyzing energy-saving modification opportunities
  • Prioritizing strategies that will have the greatest impact
  • Presenting a report in person

The report includes:

  • Description of energy-consuming systems
  • Twelve-month billing analysis
  • Determining energy consumption by end use
  • Benchmarking of energy use and cost against peer facilities
  • Energy-saving recommendations with estimated costs and financial metrics
  • If further analysis is recommended, Alliant Energy offers a Feasibility Study ?as a next step.

How do I qualify?

Audit must be conducted in a building that Alliant Energy supplies the primary heating or cooling energy.
